Nextcloud Android App - Automatically Sync Files & Folders

So near…

I use an encrypted file system and store the encrypted files in a subfolder of my nextcloud folder on a Linux machine. The Nextcloud desktop client syncs these to my server and from there to other desktop clients (Windows and other Linux PCs). If I need to I can then decrypt and access the valuable contents on those other machines.

With the Android Nextcloud client I can manually sync the crypt folder to get a local copy. I can also mark existing files as ā€˜favourites’ and I’ve found that changes to the underlying clear text files will then remain in sync in the background. However, if the encrypted file system on a PC creates a new file it is not marked as a ā€˜favourite’ on the Android client and so will not be synced by the background processing.

It seems to me that for my use case being able to mark a folder as a ā€˜favourite’ such that any new files created in it are automatically marked as ā€˜favourite’ would solve my problem.

One obvious other way around it for me is to use a container file based encrypting file system and mark the container file as ā€˜favourite’ - but that introduces other problems.

For the moment I’m back to using syncthing (which is an excellent utility) in a separate folder branch - but I’d rather consolidate to the brilliant and more generally useful Nextcloud and not have so many apps running on my phone or PCs.
